Answer:
C - (x + 2)^2 + 5
Step-by-step explanation:
C is the answer because in order to get x^2 you need to multiply x twice like this x * x = x^2 an that can be clearly stated in C as it says (x + 2)^2 then ad the end of the original equation x^2 + 2x + 5 it has + 5 at the end meaning there will be a + 5 at then of the next equation which is stated in answer choice C (x + 2)^2 + 5
